The present invention provides a system for a building envelope such as a wall or roof, comprising:
a substructure generally arranged in the plane of the building envelope;
at least a first cassette and a second cassette, each having a major plate extending in substantially the same general plane as each other and substantially parallel to and extending across the width of and attached to the substructure, top and bottom plates extending substantially perpendicularly from substantially the top and bottom respectively of the major plate away from the substructure, and downwardly directed flanges extending from substantially the distal ends of the top and bottom plates, the second cassette positioned adjacent to the first cassette such that the top plate of the first cassette faces the bottom plate of the second cassette and such that the flange of the bottom plate of the second cassette overlaps the flange of the top plate of the first cassette;
man-made vitreous fibre batts positioned between the top and bottom plates of the first cassette and between the top and bottom plates of the second cassette; and
outer cladding comprising sheeting elements, at least one sheeting element being fixed to the overlapping flanges of the first and second cassettes;
wherein a mat comprising at least 20 and up to 95 wt % aerogel is positioned between the flange of the bottom plate of the second cassette and the sheeting element, and the mat having a compressive stress at 10% compression of at least 20 kPa or, if 10% compression is not reached before the maximum compressive stress, having a compressive strength of at least 20 kPa. A method of making a system for a building envelope, such as a wall or roof, and a cassette assembly for use in a system for a building envelope, such as a wall or roof, are also provided. |
